Summary: Predicted to enable ATPase-coupled intramembrane lipid transporter activity; ATPase-coupled transmembrane transporter activity; and xenobiotic transmembrane transporter activity. Involved in response to glucocorticoid and response to xenobiotic stimulus. Located in Golgi membrane and apical plasma membrane. Biomarker of cholestasis. Human ortholog(s) of this gene implicated in cholestasis (multiple); gallbladder disease; and liver cirrhosis (multiple). Orthologous to human ABCB4 (ATP binding cassette subfamily B member 4).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
